How this service works
Pay-per-call Base onchain data, token risk verdicts and x402 payability audits over x402 (USDC on Base).
Output
Returns a JSON object with two arrays: 'contradictions' (statements within the text that conflict with each other or with known facts) and 'unsupportedClaims' (assertions that lack evidentiary backing), enabling downstream agents or users to assess the credibility of the audited content.
Example use cases
Validate token risk whitepaper claims
“I have this token risk summary someone sent me about a Base memecoin — can you audit it for any contradictions or claims that aren't backed by evidence? Here's the text: 'This token has fully locked liquidity, a doxxed team, and passed all x402 compliance checks.'”
Check x402 API listing accuracy
“This x402 API listing claims it provides real-time Base onchain data with sub-second latency and zero downtime — can you audit that description and flag anything that looks like an unsupported or contradictory claim?”
Verify DeFi agent output before acting
“My trading agent just produced this analysis saying a Base token is low risk and x402-payable — before I act on it, can you run an evidence audit to spot any contradictions or unverified assertions in the report?”
Technical details
Endpoint
POSThttps://aether-x402.vercel.app/v1/evidence/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, pay-per-call evidence audit specifically for Base onchain data claims, token risk verdicts, or x402 payability descriptions — particularly when operating in an agent pipeline that already handles x402 micropayments in USDC on Base. Prefer it over general fact-checkers when the content is crypto/DeFi-native and you need machine-readable contradiction and unsupported-claim arrays.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 40,000 characters is rejected
- Insufficient USDC balance on Base causes x402 payment failure and no audit is returned
- Ambiguous or very short 'request' field may yield shallow audit results
- Service unavailability on Vercel deployment returns 5xx errors
